Preparation, Properties, and Applications of Aligned Ni Nanowires

This talk demonstrates an easily prepared novel material and approach to producing aligned nickel nanowires having unique and customizable structures on a wide range of substrates and the electronic, optical, and magnetic properties and applications. We believe this to be the first example of printed metallic Ni from a precursor material, and the first example of nanowire formation during reduction on a surface. This homogeneous solution can be printed using many different processes in ambient conditions, and forms aligned elemental nickel nanowires over large areas upon heating to moderate temperatures in the presence of a magnetic field, without subsequent purification or requiring the use of a template. This technique is very flexible, and allows the preparation of unique patterns of nanofibers which provides opportunities to produce structures with enhanced anisotropic electrical, optical and magnetic properties.
